My mail is now running on the server again, not the Synology. The Synology does a good job, but the spamfilters are not what I like them to be. It marks mail as spam by adding “**SPAM**” to the subject line and listing how much spampoints the message got. Not what I want. I want an unaltered mailmessage in my spambox, or no message at all. I used to have that with Postfix/Postgrey/Amavis/Spamassassin.

I installed iRedMail, basically an installer layer over the standard Linux mailcomponents. Installing is done in about 2 minutes, switching of greylisting took me more time to figure out how…. Thanks people, for such a great product.
